When it comes to generational divisions, domestically we usually categorize by a decade—Post-80s, Post-90s, Post-00s. But the approach in the United States is a bit different—they use a 16-year cycle, and each generation has its own specific name.

So how are they divided exactly? The Silent Generation consists of seniors over 80 years old, while the Baby Boomers (61 to 79 years old) are a large group, representing the post-war baby boom. Generation X includes those aged 45 to 60, born between 1965 and 1980, and in 2025, they will be right in this age range. Moving on, Millennials (born 1981 to 1996) number over 70 million, and Generation Z (born 1997 to 2012) also has over 70 million, maintaining a relatively stable population. Those born after 2013 are called Generation Alpha, and after 2028, it will be Generation Beta.

Interestingly, the US population structure appears quite balanced—there's no significant drop in the number of people in each generation. Why is that? Immigration plays a key role. Continuous immigration in the US compensates for the declining native birth rate, ensuring sustained population growth.

Comparing this to the domestic situation reveals the difference. The number of people born in the 1990s is quite large, but the Post-00s have started to decline noticeably, and the birth rate among those born after 2000 has sharply decreased. This demographic shift, frankly, will impact consumer markets, labor supply, and ultimately influence investment and economic expectations.
